Piezoelectric resonator with maximum sensitivity to external pressure stresses. The resonator includes means (2,3) for exerting nonlocalized radial compressive forces uniformly over diametrically opposed peripheral zones of the crystal (1) in which the zones occupy a predetermined sector 2 alpha of at least approximately 110 DEG and are oriented so that the bisectors (A-A) of the peripheral zones form a predetermined angle psi with the crystallographic X axis of the crystal. Depending on the value of psi , it is possible to minimize or, on the contrary, maximize the sensitivity of the resonator to the external pressure stresses. |
